Important Constants

`USDC_MINT`, `USDT_MINT`	Mainnet stablecoin mint constants.
`VAULT_STRATEGY_ADDRESS`	Default pubkey sentinel used when filtering empty strategy slots.

`VaultImpl.create`

static create(
  connection: Connection,
  tokenAddress: PublicKey,
  opt?: {
    seedBaseKey?: PublicKey;
    allowOwnerOffCurve?: boolean;
    cluster?: Cluster;
    programId?: string;
    affiliateId?: PublicKey;
    affiliateProgramId?: string;
  },
): Promise<VaultImpl>

Creates one hydrated vault client from an underlying token mint. It derives the vault PDA, fetches vault state, fetches the LP mint, and fetches the underlying token mint.

Static Methods

Method	Signature	Description
`createPermissionlessVaultInstruction`	`(connection, payer, tokenMint, opt?) => Promise<TransactionInstruction>`	Builds the program `initialize` instruction for a token mint.
`fetchMultipleUserBalance`	`(connection, lpMintList, owner) => Promise<BN[]>`	Batch fetches a user’s ATA balances for multiple vault LP mints.
`createMultiple`	`(connection, tokenMints, opt?) => Promise<VaultImpl[]>`	Batch creates hydrated vault clients from token mint addresses.
`createMultipleWithPda`	`(connection, vaultsPda, opt?) => Promise<VaultImpl[]>`	Batch creates hydrated vault clients from vault PDA addresses.

Instance Properties

Property	Type	Description
`tokenMint`	`Mint`	Decoded underlying token mint.
`tokenLpMint`	`Mint`	Decoded vault LP mint.
`vaultPda`	`PublicKey`	Vault account PDA.
`tokenVaultPda`	`PublicKey`	Vault-owned reserve token account PDA.
`vaultState`	`VaultState`	Decoded Anchor vault account state.
`seedBaseKey`	`PublicKey	undefined`	Optional base key override stored on the client.

Instance Methods

Method	Signature	Description
`getUserBalance`	`(owner: PublicKey) => Promise<BN>`	Reads the user’s vault LP balance. With affiliate enabled, reads the affiliate user PDA’s LP token account.
`getVaultSupply`	`() => Promise<BN>`	Refetches the LP mint and returns current LP supply.
`getWithdrawableAmount`	`() => Promise<BN>`	Reads on-chain time and computes unlocked vault amount from `vaultState`.
`refreshVaultState`	`() => Promise<void>`	Refetches vault state and the underlying token mint.
`deposit`	`(owner: PublicKey, baseTokenAmount: BN) => Promise<Transaction>`	Builds a transaction to deposit underlying tokens and receive LP tokens.
`getStrategiesState`	`() => Promise<StrategyState[]>`	Fetches strategy accounts for non-default strategy slots.
`withdraw`	`(owner: PublicKey, baseTokenAmount: BN) => Promise<Transaction>`	Builds a transaction to burn LP tokens and withdraw underlying tokens.
`getAffiliateInfo`	`() => Promise<AffiliateInfo>`	Fetches affiliate partner account state when `affiliateId` is configured.

withdraw passes its baseTokenAmount parameter as the program’s LP unmint_amount. Use LP token units, not underlying token units.

Helper Exports

Function	Signature	Description
`getAmountByShare`	`(share, withdrawableAmount, totalSupply) => BN`	Converts LP token share to underlying token amount.
`getUnmintAmount`	`(amount, withdrawableAmount, totalSupply) => BN`	Converts desired underlying amount to LP tokens to burn.
`calculateWithdrawableAmount`	`(onChainTime, vaultState) => BN`	Calculates unlocked amount after locked profit degradation.

Utility Exports

Function	Description
`getVaultPdas(tokenMint, programId, seedBaseKey?)`	Derives `vaultPda`, `tokenVaultPda`, and `lpMintPda`.
`getOnchainTime(connection)`	Reads the clock sysvar and returns `unixTimestamp`.
`getLpSupply(connection, tokenMint)`	Reads token supply for a mint and returns a `BN`.
`deserializeAccount(data)`	Decodes SPL token account bytes.
`deserializeMint(data)`	Decodes SPL mint bytes.

deserializeAccount and deserializeMint are defined in the source utilities but are not exported from the package root in the current ts-client/index.ts.

SOL Handling

Flow	SDK behavior
Deposit into SOL vault	Creates the user’s wrapped SOL ATA if needed, transfers lamports into it, and syncs native token state before `deposit`.
Withdraw from SOL vault	Adds a close-account post-instruction for the user’s wrapped SOL ATA.

Affiliate Support

When affiliateId is passed to create, the SDK initializes an affiliate program client and changes user balance, deposit, and withdraw account planning.

Item	Behavior
Partner token account	ATA for the underlying token mint and partner public key.
Partner PDA	Derived from vault PDA and partner token account under the affiliate program.
User PDA	Derived from partner PDA and user wallet under the affiliate program.
User LP token account	ATA for the vault LP mint owned by the affiliate user PDA.

Integration Notes

Topic	Detail
Transaction return values	`deposit` and `withdraw` return unsigned `Transaction` objects. The caller signs, simulates, and sends.
State freshness	`deposit` and `withdraw` call `refreshVaultState()` internally. For displayed balances, refresh before showing final amounts.
RPC batching	`createMultiple`, `createMultipleWithPda`, and `fetchMultipleUserBalance` use chunked batch reads for dashboards and portfolios.
Strategy withdrawals	`withdraw` chooses reserve withdrawal when reserve liquidity is enough. Otherwise it selects the strategy with the highest `currentLiquidity`.
Source and IDL drift	Use the SDK reference for public client behavior. For low-level instruction behavior, compare against the current program source.
